How to undefined LEDs and Buttons in custom code?

[Ankush]

Hi,

In my application, using BMD301 i have made one custom PCB. I am using SDK 12.0.0. In my PCB I have not used all the four LEDs. I have assigned p0.19 to the BSP_LED_0 which is required for advertising indication. all the Other BSP_LEDs i am not using . but the pins assigned to these on eval kit are used for different application. Does it make any difference?

Also I am getting some issues when i am using p0.20 for difference purpose on eval kit? D o we need to comment the definition of corresponding LEDs in pca10040. or is there any other method available apart from this.

In my custom PCB board I have assignes P0.20 as SPI clk for ADXL 362 acceleromter.

  #define ADXL_SCK              20
  #define ADXL_MOSI             0
  #define ADXL_MISO             1
  #define ADXL_CS               18

But proper configuration is not happening. Same thing I tried on eval kit and I faced same issue. Then simply changed ADXL_SCK to 3 then SPI configurations worked fine.

What is the issue with p0.20.?

Hi,

You can either create your own board file, or modify an existing one in order to add support for your custom board in the BSP module. Take a look at this answer on how to create your own board file.

You can start by modifying the LED definitions in pca10040.h board file to support only one LED:

#define LEDS_NUMBER    1

#define LED_START      19
#define LED_1          19
#define LED_STOP       19

#define LEDS_ACTIVE_STATE 0

#define LEDS_INV_MASK  LEDS_MASK

#define LEDS_LIST { LED_1}

#define BSP_LED_0      LED_1
